【発明の詳細な説明】
本発明は分流式山水管、汚水管の誤接検出方法に関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for detecting erroneous connections of branch type mountain water pipes and wastewater pipes.
分流式雨水管、汚水管とはその中を通過するものがト、
イレ、台所等からの雑排水を汚水管で、又雨水等を雨水
管でそれぞれ別個に流す方式のものである。Separate rainwater pipes and sewage pipes are the things that pass through them.
In this system, gray water from toilets, kitchens, etc. is drained separately through sewer pipes, and rainwater is drained separately through storm drains.
かかる分流式雨水管、汚水管において誤まって山水管を
汚水管に接続し、そのまま放置してお（と、大雨の後な
どに大量の雨水が汚水管内に流入する結果汚水処理設備
における処理能力をこえるのみならずマンホールから汚
水を噴出するという事態を生じる。If you mistakenly connect a mountain water pipe to a wastewater pipe and leave it as it is, a large amount of rainwater will flow into the wastewater pipe after heavy rain, and the processing capacity of the wastewater treatment equipment will be reduced. Not only does the water leak, but it also causes sewage to gush out from the manhole.
従って配管工事の際等に誤接の有無を調査する必要があ
る。Therefore, it is necessary to investigate whether there are any incorrect connections during piping work, etc.
このような誤接を調査するため、現在は家屋の雨樋、雨
水桝等から染料や着色水或いは樹脂製ボールを流し、汚
水管下流のマンホール位置に前記染料、着色水又はボー
ルが流れてくるか否かを目視する方法とか、マンホール
側から煙を送り込み、家屋側の雨樋、雨水桝等から煙が
出るか否かを目視する方法とかが一般に行なわれている
。In order to investigate such misconnections, currently, dyes, colored water, or resin balls are poured from rain gutters, rainwater catch basins, etc. of houses, and the dyes, colored water, or balls flow into the manhole position downstream of the sewage pipe. Commonly used methods include visually checking whether smoke is coming out from the manhole side, or by sending smoke in from the manhole side and visually checking whether smoke comes out from the rain gutters, rainwater catchments, etc. on the house side.
しかるに、染料や着色水を流して行なう方法にあっては
染料、着色水がマンホール位置まで達するのに時間がか
かるし、各箇所（雨樋、雨水桝等）から同時に染料、着
色水を流すと、いずれの雨水管が汚水管に誤接されてい
るかわからないため、−箇所（例えば雨樋）から流した
染料、着色水が完全に流出してしまってからでないと他
箇所（例えば雨水桝）から流すことができず、従って作
業時間が非常に長くかかるという欠点がある。However, in the method of pouring dye or colored water, it takes time for the dye or colored water to reach the manhole position, and if the dye or colored water is poured from various places (rain gutters, rain basins, etc.) at the same time, it takes time. Since it is not known which rainwater pipe is incorrectly connected to the wastewater pipe, the dye or colored water flushed from one location (e.g. rain gutter) must be completely drained before flushing from another location (e.g. rainwater catchment). The drawback is that it is not possible to do so, and therefore the work time is very long.
また雨樋から染料等を流す場合は屋根上に登らなければ
ならないため、危険な作業を伴うものである。Furthermore, pouring dye etc. from rain gutters requires climbing onto the roof, which is a dangerous task.
次にボールを流して行なう方法にあっては、上記染料等
を流して行なう方法と同様な欠点に加えてボールが途中
で詰まることがあり、その場合は誤接の検出ができない
ばかりか、雨水の流通を阻害して雨水管としての機能を
も損なわせるという欠点がある。Next, the method of pouring the ball has the same drawbacks as the method of pouring dye, etc. mentioned above, and in addition, the ball may become clogged in the middle, and in that case, not only is it impossible to detect incorrect connection, but rain The disadvantage is that it obstructs the flow of water and impairs its function as a rainwater pipe.
一方、煙をマンホール側から送入して行なう方法にあっ
ては、その煙がトイレや台所から噴出して居住者に非常
な迷惑をかける場合がある。On the other hand, in the method of introducing smoke from the manhole side, the smoke may blow out from the toilet or kitchen, causing great inconvenience to residents.
これらを改良するものとして、本出願人は特願昭５５−
５０５６号で先に出願したように、汚水管下流に音源を
配置し、雨水管の上流に伝搬されているか否かを聴取す
る方法を発明したが、この方法では汚水管内に入って音
源を設置しなければならず作業性が悪かった。In order to improve these, the present applicant has filed a patent application filed in 1983-
As previously filed in No. 5056, we invented a method to place a sound source downstream of a sewer pipe and listen to whether or not it is propagating upstream of a storm drain. This resulted in poor workability.
本発明方法はこのような点を更に改良したもので、雨水
管の下流側又は上流側に低周波音響発振器を配置して、
該発振器から発する低周波が前記雨水管の上流側又は下
流側に伝搬されているか否かにより、雨水管、汚水管の
誤接を検出する点に特徴がある。The method of the present invention further improves on these points, by placing a low frequency acoustic oscillator on the downstream or upstream side of the rainwater pipe,
A feature of the present invention is that erroneous connections of rainwater pipes and wastewater pipes are detected depending on whether the low frequency waves emitted from the oscillator are propagated upstream or downstream of the rainwater pipe.
次に本発明方法の実施例を図面に基いて説明する。Next, embodiments of the method of the present invention will be described based on the drawings.
第１図において、１は雨樋２に連設された雨水管で、こ
の雨水管１の途中個所には、雨水桝３、側溝４、マンホ
ール６等が設けである。In FIG. 1, reference numeral 1 denotes a rainwater pipe connected to a rainwater gutter 2, and a rainwater catchment 3, a side gutter 4, a manhole 6, etc. are provided in the middle of the rainwater pipe 1.
又、５は前記雨水管１とは別に（即ち、分流式）設けら
れた汚水管、７は前記マンホール６を閉塞するための蓋
、８はワイヤレスマイク、８′はヘッドホン、９は側溝
４に配置された低周波音響発振装置で、この低周波音響
発振装置９は、低周波音響発振器の一例である笛１０と
空気導入のベローズ式圧入器１１と空気を貯蔵するタン
ク１２とタンクより笛に空気を送給する空気パイプ１３
とからなっており、前記圧入器１１を押圧して空気パイ
プ１３より空気を笛１０に送り音つまり低周波を発生す
る。Further, 5 is a wastewater pipe provided separately from the rainwater pipe 1 (that is, a separate type), 7 is a lid for closing the manhole 6, 8 is a wireless microphone, 8' is a headphone, and 9 is placed in the side gutter 4. This low frequency acoustic oscillator 9 consists of a whistle 10 which is an example of a low frequency acoustic oscillator, a bellows type press fitter 11 for introducing air, a tank 12 for storing air, and a tank 12 that stores air from the tank to the whistle. Air pipe 13 that supplies
By pressing the press fitter 11, air is sent from the air pipe 13 to the flute 10 to generate sound, that is, low frequency.
１４は笛の外周を囲んだ空気袋で、空気パイプ１３と連
通して、圧入器の押圧によりこの空気袋をふうせん状に
ふ（らませる。Reference numeral 14 denotes an air bag surrounding the outer periphery of the whistle, which communicates with the air pipe 13 and is inflated into a balloon shape by pressure from a press fitter.
尚、笛１０に空気を送るのにコンプレッサーを用いても
よく、あるいは第２図に示すように、低周波音響発振器
１５そのものを吊り下げる等の手段で側溝４に配置する
も良い。Note that a compressor may be used to send air to the flute 10, or as shown in FIG. 2, the low frequency acoustic oscillator 15 itself may be placed in the gutter 4 by hanging or other means.
しかして前記圧入器１１を押圧するとタンク１２内に空
気を貯え一定量ずつ空気を空気パイプ１３にて送気し、
第１図に示すように笛１０にて音を発生すると同時に空
気袋１４をふうせん状にふ（らませて、雨水管１の内周
に当接させ、この笛１０にて発生した音を雨水管１の笛
位置下流側に拡散しないようにしている。When the press fitter 11 is pressed, air is stored in the tank 12 and a fixed amount of air is delivered through the air pipe 13.
As shown in FIG. 1, when the whistle 10 generates a sound, the air bag 14 is inflated into a balloon shape and brought into contact with the inner circumference of the rainwater pipe 1, and the sound generated by the whistle 10 is transmitted to the rainwater pipe 1. This is to prevent it from spreading to the downstream side of the whistle position.
この笛１０にて発生した音は雨水管１内を拡散してゆき
雨水管の上流側、即ち雨水桝３、雨樋２等に伝搬する。The sound generated by the whistle 10 diffuses inside the rainwater pipe 1 and propagates to the upstream side of the rainwater pipe, ie, the rainwater basin 3, the rain gutter 2, etc.
従って作業者は、雨水桝３に耳を傾け、笛からの音を直
接聴くことにより、或いは雨樋２から前記マイク８、ヘ
ッドホン８を介して音を聴くことにより、汚水管とは誤
接されていす正しく接続されていることがわかり、簡単
にして確実に誤接を検出することができるのである。Therefore, by listening to the rainwater pipe 3 and directly hearing the sound from the flute, or by listening to the sound from the rainwater gutter 2 through the microphone 8 and headphones 8, the worker can avoid connecting the sewage pipe by mistake. This makes it possible to easily and reliably detect incorrect connections.
この場合、笛１０外周の空気袋１４をふくらませて、雨
水管１の内周に当接させることにより、音が地上に拡散
することは少なく、従って、たとえばそのような拡散し
た音を雨水Ｍ３あるいは雨樋２からの音と感違いする。In this case, by inflating the air bag 14 on the outer periphery of the whistle 10 and bringing it into contact with the inner periphery of the rainwater pipe 1, the sound is less likely to be diffused on the ground. I don't think it's the sound coming from gutter 2.
そして、笛１０の音つまり低周波は、管内での伝搬距離
が大で、かつ、管路途中に拡径や縮径の径変化部あるい
は曲がり部が存在していても伝搬しやすい性質を有して
いるので、雨水桝３や曲がりの多い雨樋２等を対象とす
るに好都合である。The sound of the whistle 10, that is, the low frequency, has a long propagation distance within the pipe, and has the property of being easy to propagate even if there is a diameter change part such as an expansion or contraction, or a bend part in the pipe. Therefore, it is convenient to target rainwater basins 3 and rain gutters 2 that have many bends.
このように本発明に係る分流式雨水管、汚水管の誤接検
出方法によれば、雨水管を通じて検出するようにしてい
るので汚れが少（作業がやりやすくなる。As described above, according to the method for detecting erroneous connection of a separate rainwater pipe and wastewater pipe according to the present invention, since detection is made through the rainwater pipe, there is less dirt (the work is easier to perform).
文面がりや径変化があっても遠距離伝搬が可能である笛
等の低周波を利用するので、伝搬が確実でかつ速度も速
く、而して、短時間に作業ができ、しかも狭い場所及び
狭い管でも使用でき、従って、雨水管内部に設置するこ
とにより外部にもれる音を少なくでき、且つ音響を小に
できるから居住者に迷惑をかげることもない。Since it uses low-frequency waves such as whistles that can propagate over long distances even if the text or diameter changes, the propagation is reliable and fast, and work can be done in a short time, even in narrow spaces. It can be used even in narrow pipes, and therefore, by installing it inside a rainwater pipe, it is possible to reduce the amount of sound leaking outside, and since the acoustics can be made low, it does not cause any inconvenience to residents.
